bricks, while still in t-he molds may be im-J pressed with the trademark, name or the like of the manufacturer. ,l

An object of the present invention is to provide a device, which may be easily oper-l ated upon the bricks before they are removed from the mold, and withoutv interfering with the operation of the brick molding machine,

and alsowithout the necessity of performing a number of various operations for applyingA the trademark, and which tend to destroy or injure the bricks. y

Another object of the invention is to provide a stamping or marking device. of this character which may be used Vfor impressing a plurality of bricks simultaneously, and which is always in position for application to the bricks immediately the bricks are molded and about to be discharged from the brick making machine. Y

The invention alsoaims at a device, which may bebrought intooperation at a suitable time during the making of the bricks,l by either manually, automatically or otherwise actuating the device tobring it into Contact with the freshlymolded bricks, while in the molds .and wherein the device will be auto* matically moved into position-.out of the way,

so that the molded and impressed bricks may be removed from the machineand the machine. carry on itsoperations without interference or delay. y j.

Vith the foregoing and lother objects `in View, the. invention will be more fullyr described hereinafter, and will be more* particularly pointed outin thev claimsappended hereto.

Figure 1 is a fragmentary front elevation Vof a brick molding` machine having the cement brick stamping device applied thereto and in raised position out of the way,

Figure 2 is a fragmentary side elevation of the same, and in the same position out of the way, and

mold, which maybe of any suitable si'zeand contain any ynumber of compartments, such as n is common in the-multiple brick molding ma-V chines", which are now commonly used.

The mold 10 is: supportedupon standards 11 or the like which form a part of the ,Ina-v chine and is held vand adjust-ed in proper po-` sition by the bars orl links 12 in the ordinary manner. Above the mold 10 is disposed a materialhopper 18 adapted. tobe shifted horizontally back mediat'ely overthe moldlO, as shown in Figure 2 into a rear position on the guide 14. lVhen in the rearmost position the material hopper 13 frees the mold 10, so that the bricksv f therein may be discharged'upon apallet and removed from the brick machine.

1n vertical alinement with the mold 10, and registering with the various compartments which may be formed in themold 10, is a pluandforth from a position imf rality of plungers 15` adapted to operate upon v the. material. and compressthe same inthe mold 10 `to form the bricks. These plungers 15 are mounted on plunger rods or barslG suitably supported inthe super-structure of the frame 1 t lVhen thematerial hopper 13.1is shifted backwardly, fthe upper side of the mold: 10 is` exposed, so that the molded bricks therein'are l'exposed through the'upperside of the mold 10. Advantage' is taken of this operation of sok the machine,.so as to stamp or impress these` freshly molded bricks while still in the mold, so that stamping pressure exerted upon the bricks will not tend to distort, destroy orz otherwise injure the bricks. To this end, the

material hopper 13'is used as a carrier for a stamping plate-18, which is hingedalong one edge by hinges 19v to the lower front edge of the materialhopper 13. The hingesh19v may be of any suitable type and number V'to connect the stampingV plate 18 to the material hopper, so that the plate may be swungup and down into raised and lowered positions,I

and at the same time will be carried'back and forth with the material hopper. The plate 18 is of suchdimensions that when the material hopper 13 is moved into a rear position, the plate 18 will overlie and substantiallycover the top of the mold 10. A plurality of dies 19 of the projecting type are mounted upon the Vunder side of the plate 18 opposite each compartment in the mold 10 and` projects sutliciently to engage in the upper faces of the bricks which are in the mold when the plate 18 is forced downwardly over the open top of the mold. Y kThe stampingplate 18 is normally held in the raised position, as shown in Figures 1 and 2, by one or more springs 20. In the present instance a spring 2() is connected at its lower end to each end of the plate 18, and the plate 18 has a projecting lug 21 at each end and nearv its free edge to receive the lower end of the springQO. The upper ends of the spi'ings 20 are suitably connected to the frame 17 or super-structure o f the brick making machine. It is apparent that the plate 18 may be swung downwardly by hand or by "any other suitableimeans,

either automaticallyV ,ori otherwise at the proper time during the operation of the brick making machine, Sotliat'the mold is first filled, the block compressed in the compart- 7 ments ofthe molds, and the material hopper moved out of the way to expose the freshly molded bricks through the top of the mold.

At this point in the operation of the maf chine the plate 18 is operated upon to swing the plate 18 downwardly and force the proi jecting dies 19 into the upper surface of the freshly moldedbricks. The mold holds thepbricks in proper shape during this imi pression.

The dies 19 may be of any suitable character to impress the naine of the4 maker, his trademark, or any other suitable data or markings which it is desired to impress upon the bricks. It is apparent that one downward swinging of the plate 18 impresses the entii'e number of bricks which are contained in the mold 10. The projecting arms or lugs 21 at the'ends of the plate 18 provide handles or the like by means of which the plate is forced downwardly by application of pres` sure to the arms 21, the springs 20 acting on the arms 21 to return the plate 18 into its normal raised position. 4

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifi-i cally described embodiment of this invention without departing from the spirit thereof,

`such changes and modifications being restricted only by the scope of the following claims.

W'hat is claimed is n 1; A stamping device for application to brick making machines having a mold, a

shiftable material hopper for movement into and from position over the mold, and a superstructure above the mold, comprising a plate hinged to the front of said material hopper mold, said plate adapted to be forced downwardly over said mold to embed said dies in the newly formed bricks in the mold.

,2. A stamping device for application to brick molding machines having the usual mold andinaterial hopper, afplate hinged to the forward edge of said `hopper adapted to be shifted into position over themold when the hopper is withdrawn therefrom, springs normally maintaining said plate in 'a raised position, and stamping dies mounted upon the' under side of the plate for projection into the mold wheny the plate is lowered to impress newly molded bricks while still in the mold, said plate adapted to be moved downwardly when said from the mold.y l

3. A stamping device for application to brick making machines having a mold, a hopperfoi fittingl material to the'mold and movable into and outof position over the mold, and a. super-structure above the hopper and the mold, a plate hinged along one edge to the' lower edge of the hopper and movable into and out of position over the mold during the `per shiftable into and out of position between the mold and plunger, a, plate movably mounted on the hopper for movement into and out of position over the mold by the shifting of the hopper, and a die carried by said plate, said plate adapted to be moved against the mold for pressing the die in a brick in the mold when theplate registers with the mold.

In testimony whereof I affix my signature.
